Detailed Review
Reson8 is a speech recognition service run by Resonate Labs B.V., a Dutch private company with its statutory seat in Amsterdam at Keizersgracht 264. The terms give Dutch Chamber of Commerce number 98891340.
Reson8 positions its models for regulated industries. The home page lists English, Dutch, French, German, Italian, Polish, Brazilian Portuguese, Spanish, Swedish and Frisian as native-grade languages.
How does Reson8 handle domain vocabulary?
Reson8 says its recognition adapts to a domain from a text upload or in real time, without audio samples or fine-tuning. Medication names, order numbers, addresses and case references are the examples it gives.
The terms describe a Terminology List, a list of domain terms the customer uploads, and a Custom Model created through Reson8's context biasing adapter.
Where does Reson8 process audio?
The home page claims 100% GPU processing in the EU and zero audio retention. The privacy policy, last updated 22 October 2026, says customer audio and transcripts are processed on behalf of customers under a Data Processing Agreement.
The pages we read do not list data centres or sub-processors by name, so ask for the Data Processing Agreement before sending sensitive audio.
Reson8 as a European alternative to Deepgram
Reson8 offers an EU-only entity and processing claim where Deepgram's terms follow California law. The banner price of EUR 0.01 per hour for the Rumble-2-Flash model is very low, but it covers prerecorded audio only.
Deepgram is stronger on breadth, with text-to-speech and a voice agent API next to transcription. Compare with Voxist if you also need translation and synthesis.
Limitations to Consider
The pricing page could not be read as text, so the full rate card, free tier and streaming prices are not confirmed. The banner price applies to prerecorded transcription. The company is young, the terms and privacy policy were updated in October 2026, and the pages we read show no certifications or named hosting provider.
Who Should Use Reson8
European developers and regulated teams that need accurate domain terms and a Dutch contracting entity, and who can accept a newer vendor.
